History
Monica was developed at the Bomber Support Development Unit (BSDU) in Worcestershire.Template:Cn After the Luftwaffe became aware of Monica from a crashed bomber, German scientists developed a passive radar receiver, named Flensburg (FuG 227). From early 1944, FuG 227 was used by nightfighter crews to home in on Allied bombers using Monica.<ref>Price, p. 100.</ref> However, on the morning of 13 July 1944, a 7.Staffel/NJG 2-flown Junkers Ju 88 G-1 nightfighter equipped with Flensburg mistakenly landed at RAF Woodbridge. After examining the Flensburg equipment, the RAF ordered Monica withdrawn from all Bomber Command aircraft.<ref>Price, p. 154.</ref> An AN/APS-13 was used as a radar altimeter during the Atomic bombings of Hiroshima and Nagasaki by the 509th Composite Group, USAAF.
